Aim of the present study is Identification of specific gene for GPCR using specific primers .and identification of difference in PCR analysis in patients with heart thrombosis and compared with healthy, Sequencing of PCR product regarding GPCR compared for all three subject, Identification the similarity of human GPCR with local strain of yeast fifty healthy control and fifty patients with thrombosis which diagnosed medically with cardiac specific troponin t, troponin 1 levels and electro myocardiogram ECG. The aged for all subjects ranged (39-75) years patients were lying in cardiac care unit at Ibn- al- Nafees teaching hospital and Sheikh Zayed teaching hospital. Genomic DNA of whole blood was extracted from buffy coat and cell cultured handbook protocol using Bioneer- kit and Genomic DNA fungus/yeast kit was used in isolation and purification of DNA. patients divided into three groups according to their age: group A (60-75) years , group B (50-59) years , group C (39-49) years the results of genomic DNA isolation from blood cells extracted in pure form which ensured by the absorbance ratio (260/280 ) was (1.6 – 1.9 ) with a concentration of 50µg/ml and one DNA band with high resolution in gel electrophoresis. The result of genomic DNA extracted from the local strain of S. cerevisiae showed that DNA extracted with high purity because the absorbance ratio (260 /280 )was (1.7 to 2.0) with a concentration of 60 µg/ml and presence one DNA band with high resolution in gel electrophoresis. primers were designed depending on the sequence of the gene responsible for the production of GPCR on the chromosome 11 , GPCR contain three exons which covered with six primers to detect a defect in gene sequence among. Results of gel electrophoresis are showed that primer GPRX1 gave one band for (Control , A,B ) groups but absent amplified band in the patient eight and nine from group C. with molecular weight of this band is 1000 bp. The GPRX2 primer used to amplify second exon in the GPCR gene ,the molecular weight of amplified bands are 400 bp were present in all control samples and three groups of thrombosis patientsand yeast. GPRX2A primer that designed to amplify part two from second exon of GPCR gene by PCR gave one band for all samples which include control and patient, the molecular weight of this band is 500 bp. PCR analysis showed one amplify band for all control and patients group with molecular weight 500 bp for GPRX3 primer and 400 bp for GPRX3A ,300 bp for GPRX3B. The specific primers which designed to covering GPCR gene used to amplification genomic DNA of the local strain S.cerevisiae by PCR technique. Results showed all six primers which gave one band with difference molecular weight for each primer. All samples demonstrate identity planned sizes to control and local strain of S. cerevisiae samples except patient number 8 and 9 in the group(C) that showed non specialist bands in specific primer with first exon (GPRX1) .So the genetic sequence analysis of these two case based on the sequence of the remainder exons to detect the genetic defect in these case. The sequence of the first part for the second exon (X2) was identity standard sequence found on the NCBI web site for case( 8). The case (9) showed identity with the sequence present in the human gene bank but some difference in the first of sequence which neglected because it is in the place link of primer. The results for case 8 showed some mutation for Exon X2(part2). but case (9) demonstrate one deletion and one substitution. The results, also, illustrated that the ether48 thrombosis patients didn't appeared any mutation despite the positive results for ( Troponin) that gives strong indication of thrombosis. The conclusion Primer GPRX1 gave one band for (Control , A,B ) groups but absent amplified band in the patient eight and nine from group C. The molecular weight of this band is 1000 bp. The amplified band with molecular weight 400 bp were present in all control samples and three groups of thrombosis patients with primer GPRX2 and 500 bp with primer GPRX2A.PCR analysis showed one amplify band for all control and patients group with molecular weight 500 bp for GPRX3 primer.,400 bp with GPRX3A and 300 bp for primer GPRX3B.Similarity between results given by healthy group and local strain of yeast. Genetic study showed that there are only two case of patients eight and nine demonstrated mutation in nucleic location on exon two and three from GPCR gene
Polyphenol oxidase (PPO) is an enzyme containing copper, presents in various fruits and vegetables. It is responsible for the browning reactions when the cells are damaged during handling. The best conditions for extraction of polyphenol oxidase from banana peel was by using an extraction buffer containing phosphate buffer (0.05 M, pH 7), 0.01 M ascorbic acid and 0.5% polyethylene glycol, with extraction ratio 1:4 (w:v) for one minute by using blender. The enzyme activity was measured spectrophotometrically at 425 nm. PPO was studied to prevent the browning of banana peel which results in the loss of their marketability. The aim of this study was to determine the optimum conditions for polyphenol oxidase extraction from banana peel.

Several industrial wastewater streams may contain heavy metal ions, which must be effectively removal
before the discharge or reuse of treated waters could take place. In this paper, the removal of copper( II)
by foam flotation from dilute aqueous solutions was investigated at laboratory scale. The effects of
various parameters such as pH, collector and frother concentrations, initial copper concentration, air flow
rate, hole diameter of the gas distributor, and NaCl addition were tested in a bubble column of 6 cm inside
diameter and 120 cm height. Sodium dodecylsulfate (SDS) and Hexadecyl trimethyl ammonium bromide
(HTAB) were used as anionic and cationic surfactant, respectively. Ethanol was used as frothers and the

The aim of this research is to benefit from recycl the aircraft waste oils which is discarded in sewage network, to be used in preparation of greases for industrial purposes and to reduce the environmental pollution. In this research synthetic greases were prepared with special specifications by mixing the waste oils after treating with (silica gel as adsorbent agent, and filtration to precipitate impurities then heated to 110 C? to get rid of water) bentonite produced in Iraq which is available and cheap with existence of high density polyethylene at specific conditions of ( heating and mixing) . The best weight proportion were reached, then paraffin wax and additives were added to improve the properties of grease and give the

Polyvinyl alcohol, (PVA) was prepared using polyvinyl acetate emulsion (manufactured by Al-Jihad factory,
That-Al-Sawary Company) as a local raw material. In this investigation, polyvinyl acetate emulsion was converted to
solid form by coagulation the polymer from its emulsion using sodium sulphate salt as coagulant aid, then alcoholyzed
the solid polyvinyl acetate in methanol using sodium hydroxide as catalyst, polyvinyl alcohol produced by this method is
a dry, white to yellow powder.
Three affecting variables on the degree of hydrolysis of PVA were studied, these variable are Catalyst to
polymer weight ratio in the range of 0.01 – 0.06, reaction time in the range of 20 – 90 min, and reaction temperature in

The ability of pulverized walnut-shell to remove oil from aqueous solutions has been studied. It involves two-phase process which consists of using walnut-shell as a filtering bed for the accumulation and adsorption of oil onto its surface. Up to 96% oil removal from synthetic wastewater samples was achieved while tests results showed that 75% of oil can be removed from the actual wastewater discharged from Al- Duara refinery in the south of Baghdad.
The family Pholcidae represented by the species Artema doriae )Thorell, 1881) is recorded in Iraq for the first time.So far, 23 families of spiders have been recorded in Iraq.
In this paper, we add a new family and a description of a species belonging to this family in the checklist of Iraqi spider fauna.
